METHOD OF MANUFACTURING BUILDING BLOCKS OR BRICKS AND GLASS FACINGSTHEREFOR.

Specification of Letters Patent.

Patented March 16, 1909.

Application filed. June 5, 1908. Serial No. 436,941.

T 0 all whom it may concern:

Be it known that I, EDWARD KAYE, a citizen of the United States,residing at Monaoa, in the county of Beaver and State of Pennsylvania,have invented certain new and useful Improvements in Methods ofManufacturing Building Blocks or Bricks and Glass Facings Therefor, ofwhich the following is a specification.

This invention has relation to methods of manufacturing building blocksor bricks and glass f acings therefor and has for its object a a novelmethod of manufacture whereby time, labor, material and expense aresaved and a plurality of novel and useful glass facings aresimultaneously produced by a single pressing or blowing operation, whichfacings are ultimately employed as component parts of a plurality ofbuilding blocks or bricks.

In carrying my method into effect I press, or blow, in a suitable mold,a mass of glass to rectangular box-like form, open on one side and thenseparate this mass into two halves, each of which constitutes a facingfor a building block or brick, each such facing having a front wall, abottom, and two end walls. The facings so produced are ultimatelyprovided with a filling and backing of cement, concrete, ceramic orother suitable substance, so that eachfacing will constitute a componentpart of a complete building block or brick.

In pressing the facings, I preferably form a breaking line therein byforming a groove along the center of the bottom and he end walls of thebox-like mass during the pressing operation as such breaking linegreatly facilitates the separation of the mass into the two halves whichconstitute the two facings, but it will beunderstood that other wellknown means may be employed for facilitating the separation of the massinto the desired parts, such, for instance, as by cutting the mass alongthe desired line by means of a diamond.

l have shown in the accompanying drawing sufficient apparatus to enableothers skilled in the art to practice my improved method and have alsoshown the pressed or molded glass mass before it has been separated intotwo facings and have also shown two building blocks or bricks of whichthe facings constitute component parts and in the drawings: Figure 1 isa vertical sectional view of a mold with the completed facing therein.of the mold, with the facing therein and the plunger omitted, on line ofFig. 1. Fig. 3 is a perspective view of the two pressed or moldedfacings before being separated. Fig. 4 is a vertical transverse sectionof two building blocks of which the pressed or molded facings shown inFig. 3 constitute component parts. Fig. 5 is a sectional view of themold for forming the cement backing and filling in the facing.

The mold for forming the mass of glass to the form required to make twofacings simultaneously at a single pressing operation may be of anysuitable form, that which I have illustrated being composed of the sides1 and the ends 2 and the bottom plate 3. The sides 1 and the ends 2 areinwardly inclined on their inner surfaces from near their upper edges tonear their loweredges as shown at 4 and are cut away at the lower end ofthe inclined surfaces, as shown at 5 so that the mass of glass formed inthe mold will have a groove 6 formed in it adjacent to that portionwhich is at the bottom of the mold, this groove being preferably oftriangular form and leaving a flange 7 all around the mass of glass, thegroove serving, in the completed building block or brick, to provide arecess for the reception of the mortar or cement in which the buildingblocks are laid in constructing walls, floors or facings. If desired themold may also be provided with projections designated 8 which formrecesses 9 at the bottom of groove 6, these recesses providingadditional binding means for the mortar or cement in which the buildingblocks or bricks are laid. i

The bottom plate 3 of the mold is formed with a horizontal rib 9 and theends 2 of the mold are formed with vertical ribs 10, these ribs servingto form a deep groove 11 in the mass of glass at that portion which isat the bottom of the mold and which subsequently becomes the fronts ofthe two facings and similar groove 12 on the two ends of the mass ofglass, the grooves on the end and the grooves on the bottomconstitutinga breaking line by reason of the diminution of thickness ofthe walls of the mass of glass and facilitating the separation of thelatter to form two complete facings as Will be hereinafter described. x

The mass of glass, designated 13, is pressed in the mold by means of aplunger 14 of ap- Fig. 2 is a horizontal sectional view after separatedinto two halvesby breaking it apart along the breaking line and the twohalves of the blank then constitute two complete facings for twobuilding blocks or bricks.

A suitable manner of completing the building blocks or bricks isillustrated-inFig. 5, in which one of the facings produced in the mannerabove described is shown in position in a mold 15 with that part of thefacing which is to form the front of the brick at the bottom of themold. After the facing has been placed in the mold to the required depthwith cement, concrete or other suitable material 16, which is, ifnecessary, tamped, pressed or otherwiseproperly compacted and thenallowed to dry,

the cement or other material adhering to-the facing and the wholeconstituting when completed 1n the manner described a complete buildingblock or brick with a glass facing and a cement or other suitablebacking. The other half of the blank is similarly provided with afilling and backing and thus two complete building blocks or bricks,each having a glass facing, are formed from a single blank by providinga suitable backing and filling for each half of the blank, two suchcomplete blocks or bricks being shown in Fig. 4 of the drawing.

15, the latter is filled Vlhilel have described the completebuilding-blocks orbricks as being formed by packing a primarily plasticmaterial into and adj-acentthe glass facing so as to form a selfadherent filling and backing piece for the glass facing, it is obviousthat the filling and backingpiece could be formed separate from thefacing and then, after it had hardened, could be cemented or otherwiseattached to the facing, made of wood, stone or other solid material outor otherwise formed to the desired shaae and then connected or otherwisesuitab y attached to the facing.

I claim:

1. The method of making building blocks or bricks consisting in forminga blank comprising a plurality of connected facings, then dividing theblank into a plurality of sections each constituting a complete facing,then applying to each facing while the l'acings are in hardenedcondition a suitable unheated filling and thereby forming a plurality ofcom' pleted building blocks or bricks.

2. The method of making glass-faced building blocks or bricks consistingin forming a blank comprising a plurality of connected facings, thendividing the blank into sections, each constituting facing, thenapplying to each facing a filling of cold plastic material of suitableform and allowing the latter to dry, thereby completing a plurality ofbuilding blocks.

In testimony whereof I have affixed my signature, in the presence of twowitnesses.
